3 piece rocker??
 

Hey guys. I'm looking to replace my old ram with an 05. The new one has a badly repaired rocker panel. When i look to replacement panels, i see
an inner and outer. My question is this. Where do i find the center part of the rocker. There's an inner, outer, and an (inner/inner??). I'm guessing it's where most of the support comes from. But i can't find any repair pieces for this. Is it part of the rockers or part of the cab?? Thanks
